RSU Tax Questions. Answered directly.

RSUs are taxed as ordinary income in the year they vest — not when granted and not when sold. The fair market value of shares on the vest date is added to your W-2 income. The combined federal and California marginal rate on RSU income ranges from roughly 47% at $400K total income to 52% at $1M+. Federal ordinary income rates are 35–37% (the 37% bracket begins above $626K for single filers). California rates are 9.3–13.3% (the 13.3% rate begins above $1M). Medicare adds up to 2.35%. California does not offer a preferential capital gains rate.

You owe tax in the calendar year your RSUs vest — regardless of whether you sell the shares. Your employer withholds taxes at vest (commonly at the 22% or 37% supplemental rate), but this withholding is often insufficient for California high earners. Any gap between withholding and actual tax owed is due April 15 of the following year, with potential underpayment penalties if quarterly estimated payments weren't made during the year.

It depends on your total income for the year. At $400K total (e.g., $180K salary + $220K RSU), the marginal rate on the last dollar of RSU is approximately 47.65%: 35% federal (the 37% bracket doesn't start until $626K for single filers in 2025), 10.3% California (the 13.3% bracket doesn't start until $1M), and 2.35% Medicare. At $700K+ total income, you hit the 37% federal bracket; at $1M+, you hit the 13.3% CA bracket, and the combined rate reaches approximately 52.65%. California is one of the highest-tax environments in the country for ordinary income.

Selling immediately at vest is the most common default — and often not optimal. The argument for immediate sale is that holding adds concentrated single-stock risk on top of your salary, bonus, and career exposure to the same company. The argument against immediate sale is that doing so in a high-income year triggers full marginal rates, and waiting for a lower-income year or deploying offset strategies can meaningfully reduce that rate. The optimal answer is a quantitative analysis of your specific income, vesting schedule, and available strategies — not a blanket rule.

Unvested RSUs are typically forfeited when you leave. Vested RSUs are yours and can be sold at any time. Some companies accelerate vesting upon involuntary termination in a change of control — review your grant agreements. The timing of a departure relative to a cliff vest or quarterly vest date matters enormously: leaving two weeks before a large vest forfeits those shares. If you're considering leaving, model the vesting calendar before setting a departure date.

Employer withholding on RSU vesting is often insufficient for California high earners. If total tax owed exceeds withholding by more than the safe harbor amount (generally 100% or 110% of the prior year's tax liability), you may owe underpayment penalties. Quarterly estimated payments due in April, June, September, and January of each tax year can prevent this. In a year with a large vesting event, your advisor or CPA should calculate appropriate estimated payment amounts based on projected income and withholding.

Yes. Several strategies can meaningfully reduce the tax burden: Oil and Gas working interest investments generate immediate ordinary income deductions in the same calendar year as vesting. Qualified Opportunity Zone funds defer recognized capital gains. Short-term rental investments with cost segregation studies generate accelerated depreciation deductions classified as active business losses. Charitable Lead Annuity Trusts produce large upfront charitable deductions. Donor-Advised Funds allow appreciated stock contributions without capital gains recognition. The right combination depends on income level, liquidity, timeline, and risk tolerance.

Oil and Gas working interest investments generate Intangible Drilling Cost (IDC) deductions — typically 60–80% of the investment amount — deductible against ordinary income in Year 1. At a combined marginal rate of 47–52% (depending on your total income), $100,000 in deductions saves approximately $47,000–$52,000 in taxes. The investment also carries economic return potential from production revenue. Key considerations: these are illiquid investments with commodity price risk. They are not appropriate for everyone. We only recommend operators with audited historical track records.

A QOZ fund allows investors to defer capital gains by reinvesting them within 180 days of recognition. Federal tax on the deferred gain is due when the fund is sold or December 31, 2026, whichever is earlier. Appreciation in the QOZ fund itself is federally excluded from capital gains if held 10+ years. Important for California taxpayers: California does not conform to federal QOZ treatment. The gain deferral and exclusion apply federally, but California taxes the gain as if the QOZ investment never happened. QOZ funds are most useful for absorbing capital gains from concentrated stock sales, not directly from RSU ordinary income.

A DAF allows you to make an irrevocable contribution of assets — including appreciated stock — and receive an immediate charitable deduction for the full fair market value, without recognizing capital gains on the appreciation. The DAF sells the shares, pays no capital gains tax, and invests the proceeds until you recommend grants to qualified charities. For RSU shares that haven't appreciated since vest, the deduction equals the current value against ordinary income. DAFs are easy to establish and offered by Fidelity Charitable, Schwab Charitable, and Vanguard Charitable, among others.

An acquisition payout creates a forced, concentrated ordinary income event. Strategies that can reduce the tax burden in that specific year include: Oil and Gas investments (immediate ordinary income deductions), Charitable Lead Annuity Trusts (large upfront deductions), DAF contributions, maximizing 401k and Roth contributions, and QOZ investments for any capital gains portion. The window to plan before close is often short — advance planning is essential. Late-stage deal negotiations may also offer limited structuring options worth evaluating.

A concentrated position — generally above 20% of investable assets in a single stock — represents risk many tech employees underestimate because the position grew quietly over years of vesting. Selling outright in California triggers the highest possible rates. Tax-efficient alternatives include 721 exchange funds (contribute shares to a diversified partnership without a taxable event), 351 exchanges, charitable strategies via CLATs or DAFs, and systematic partial sales in lower-income years with offset strategies. A 3-to-5 year rolling exit plan typically produces better outcomes than a single-year liquidation.

A 721 exchange fund (contribution fund or swap fund) is a limited partnership that accepts contributions of appreciated securities in exchange for diversified partnership interests — without triggering an immediate capital gains tax. The gain is deferred until the investor redeems or sells. Eligibility typically requires: qualified purchaser status (generally $5M+ investable assets), a 7-year minimum holding period in the fund, and the contributed shares must meet diversification and eligibility requirements under IRC Section 721. Not all stock qualifies — closely-held shares, restricted shares, and certain recently vested RSUs may not. A position-level analysis is required to determine eligibility.

California taxes long-term capital gains as ordinary income — there is no preferential capital gains rate. A gain taxed at 0% or 15% federally is still taxed at up to 13.3% in California. This makes QOZ funds and other federal capital gains deferral strategies more valuable for California residents (they reduce a higher combined burden) but also means the strategies must be evaluated for California treatment separately. California does not conform to several federal provisions that reduce capital gains tax, including the QOZ exclusion.

RSUs are taxed as ordinary income at vest — straightforward. ISOs have no ordinary income tax at exercise, but the spread is an AMT preference item, which can trigger significant AMT liability. ISO gains qualify for long-term capital gains rates (federally) if held for 2 years from grant date and 1 year from exercise date — but California taxes ISO gains as ordinary income regardless. Optimal ISO exercise strategy — how many shares, in what year, at what price — requires modeling AMT exposure, California income, and your RSU vesting calendar together.

ESPP shares have complex mechanics that interact with RSU income. A disqualifying disposition (selling before 2 years from offering date and 1 year from purchase date) triggers ordinary income on the discount — which compounds with RSU vesting income in the same year and can push you into higher brackets. A qualifying disposition receives more favorable treatment: the discount is ordinary income but any additional gain above the purchase price is a long-term capital gain (federally). ESPP planning should be coordinated with RSU sequencing to prevent unintentional bracket creep.

Multi-employer RSU situations — common when changing jobs while holding vested shares from a prior employer — require a consolidated inventory of all positions across both companies. Key planning considerations: selling prior employer shares in the same year as new employer vesting compounds income in a single year; each company's shares have different lot-level cost bases, holding periods, and concentration implications; and resale restrictions or lock-up periods from the prior employer may limit your flexibility. A full equity compensation inventory across all employers is the starting point.

A fee-only advisor is compensated exclusively by client fees — no commissions, referral fees, or product revenue sharing. This matters for RSU planning because the strategies commonly used to reduce vesting taxes — Oil and Gas investments, exchange funds, QOZ funds, CLATs — often carry embedded commissions for advisors who are not fee-only. A commission-based advisor may receive 7–10% of an Oil and Gas investment as compensation. A fee-only fiduciary has no financial incentive to recommend any particular product and is legally required to act in the client's interest.

General financial planning covers retirement projections, insurance, portfolio allocation, and broad tax considerations. RSU planning for California tech employees is a specialization that requires deep familiarity with vesting mechanics and lot-level cost basis analysis, California tax law including its non-conformity to federal provisions, Oil and Gas partnership structure and IDC deduction mechanics, exchange fund eligibility and 7-year holding requirements, QOZ fund timelines and California non-conformity, depreciation planning for short-term rentals, and multi-instrument equity compensation interaction modeling. Most generalist advisors see tech employees but don't specialize in the intersection of all these elements.

The most useful inputs for a first consultation are: your equity compensation summary from your HR or equity portal (vesting dates, grant prices, number of shares per grant), your most recent W-2 or a sense of your total compensation for the current year, any other income sources (real estate, side income, bonus schedule), a rough sense of your existing investment accounts and their current allocation, and any specific questions or concerns driving the conversation. You don't need to have everything organized — the first call is a conversation, not an audit.
